Car won't turn on
Yesterday, I tried to turn on my car, but nothing turned on. The engine didn't
make a noise and no lights came on. So I changed the battery and once I
did, the car worked again! I took the car out on a short 5 minute drive and left
my car alone afterwards. This morning when I tried to start up my car again, I
had the same problem as yesterday so I'm not quite too sure what's going
on. Yesterday when I changed the battery, the car honked when I connected
the cable to the negative terminal. Is that supposed to happen again? Also,
my low oil pressure light came on a few days ago but I haven't driven the car
too much after it came on. I filled up on oil yesterday. Could that sensor be
affecting my car? I removed the battery from my car and used a DMM and
found that the voltage was 7.98V. That's abnormal correct?
